The Zodiac Cigarette Code

CNN's John Sutter looks at the case of a man who was found dead on a beach in England. He says police have been unable to solve the mystery because they don't know if it is a code or not. The FBI and Scotland Yard are still trying to find out what happened, but haven't made any headway so far. A woman told investigators that she had given a book with her phone number to an army officer named Alf Boxle; he has never been identified.
